The solubility of 1-(2-dimethylaminoethyl)-5-mercapto-1H-tetrazole (DMMT) in water, N,N-dimethylformamide (DMF), methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, and 2-butanol between (293 and 343) K was measured using a laser monitoring observation techinque. The results were correlated with a semiempirical equation, the calculated results of which are proved to show fine representation of experimental data.
